The mug is BPA and phthalate free, measures 6 inches (15 cm) tall, and its base fits most cup holders; hand-washing is recommended. User reviews rate the leak-proof design and easy cleaning highly, though some note variable heat retention, a potentially stiff slider, and possible paint chipping.","url":"https://www.simons.ca/en/kitchen-dining/drinking-glasses-mugs/coffee-mugs-teacups/smoothsip-insulated-mug-12-oz--20977-5251100?colourId=45","brand":"Owala","condition":"new","product_category":"kitchen dining > drinking glasses mugs > coffee mugs teacups","material":"18/8 pro-grade stainless steel BPA-free, plastic","age_group":"adult","image_url":"https://imagescdn.simons.ca/images/20977/5251100/45/A1_2.jpg","additional_image_urls":["https://imagescdn.simons.ca/images/20977/5251100/45/A2_2.jpg"],"images":[{"id":"img-1785386937585-0","url":"https://imagescdn.simons.ca/images/20977/5251100/45/A1_2.jpg","alt_text":"SmoothSip insulated mug 12 oz. product image (primary)","position":1,"attributes":{"other":{"summary":"Product shot on a two-tone background with soft studio lighting and a visible cast shadow to the left of the mug.
